One of these "on the name of Albert Roussel" was composed by Jacques Ibert, while Carlos Chavez composed another one of these works for six percussionists.  Six of these, including two with sections labeled "discurs," were composed by Juan Cabanilles.  One of these works is titled "Little Train of the Caipira" and concludes Villa-Lobos' Bachianas Brasileiras Number 2.  Other examples include the concluding movement of Ravel's Le (*) Tombeau de Couperin and one composed by Prokofiev opens with a later-recurring theme in which the right and left hands alternately play D. Perhaps the most famous example of this form begins with an unfolding diminished seventh chord which resolves into a D major chord; that piece, beloved by Leopold Stokowski, is the first half of BWV 565. For 10 points, identify this compositional form, paired with a fugue in a D minor work by J.S. Bach.
